I only suffer with my chest when I get a cold. I have an inhaler but I don't think I used one for about 7 years now. As a kid it was horrible and the scariest moment came when I went for my check up and on that day my chest was really bad. I was packed off to a Ward to have some oxygen etc and this ward was dark and had 4 other beds in and the kids in them were just lying there wheezing away. The noise and atmosphere terrified me!.
Until I was about 14 I couldn't do anything that involved running.
Only ever seen hubby have a really bad one, terrified me. Awful when you see someone gasping for breath and inhalers are not doing shit. Must be particularly terrifying for little kids who suffer with it.
